personality is called Annamaya Kosa. This is normally nourished by the gross food (also called anna) that we consume.

This is what the modern science also has understood. It has successfully unravelled the sublities of this Kosa. In his search towards reality of the most fundamental principle of this universe, a scientist started with the external gross world of solid matter which is simple and easy to see, divide, and do experiments with. This search led him to go on discovering smaller and smaller particles starting from elements, molecules, atoms, protons, neutrons and electrons etc. He further understood that it is all pockets of energy. Our body is therefore a permutation and combination of various chemicals (i.e., pockets of energy in various configurations). When they join together they form molecules, cells, tissues, organs, etc. These follow certain well defined laws of nature and are controlled by nervous (electrical) and chemical (hormone) mechanisms to bring about movement and action in each and every cell. Thus annamaya kosa is the physical frame which is the grossest of the five bodies.

ii. Pranamaya Kosa (life energy body).

Father Varuna says " my dear son, there is something more subtle than what you have discovered, please go on and carry on with your research". Bhrgu after a long research comes back and says 'Oh, father, it is the prana - the life energy, from which even the gross annamaya Kosa comes out'. Prana the life energy described here is not the material electromagnetic energy spectrum known to modern science. All these energies like electricity, sound, light, radio, x-ray, etc. belong to annamaya kosa as they are bound by energy laws. The prana described here is subtler than that. It does not follow the laws of the usual energies. It is described as,
